SHUTTLE.

Application filed January 21, 1916.

To all w wm t may concern.'

Be it lniown that I, Josnrn F. VArLLAN- coUn'r, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful improvements in Shuttles, of which the following is a specification.

This invention relates to improvements in shuttles for looms, one object of the invention being the provision of a shuttle, in which the thread is guided through the bottom thereof, and toward the point of the shuttle. l

A further object of the present invention is the provision of a novel form of thread Aguide mounted in the nose of the shuttle, and leading inclinedly toward the nose or point, and through the bottom of the shuttle, thus preventing the thread from being cut in the shuttle boX and getting fast in the chips.

A still further object of the present invention is the provision of a shuttle that can be threaded in a sanitary manner and not by sucking or blowing as is the usual method.

Another object of the invention is the provision of a durable and inexpensive shuttle, and one which has none of the disadvantages of the old shuttle.

1n the accompanying drawings: Figure 1 is a bottom plan view of my improved shuttle. Fig. 2 is a longitudinal section through the complete shuttle. Fig. 3 is a perspective View of the metal portion of the thread guide per se. Fig. 4 is a cross section on line 4r1 of Fig. 2.

Referring to the drawings, the numeral 5 designates the body of the shuttle, having the recess 6, for the reception of the bobbin 7. rThis recess 6 opens through the top and bottom of the shuttle body 6, while in the underside or bottom is a groove or gutter 8, leading from the elliptical opening 9 of the body to the point.

The inclined bore 10 leads from the rounded portion 11 of the recess 6 to a point at the eXtreme forward portion of the groove or gutter 8, there being provided a slit 12 eX- tending from the forward end of the bore 10 through the bottom of the body 5 to the opening of the recess in said bottom.

Removably fitted, from within therecess 6, in the bore 10 is a metal thread guide 13, which as shown in Fig. 3, consists of the tubular portion 14, having the two flanges 15 Specification of Letters Patent.

.bent inwardly and spaced to provide the longitudinal groove or slit 16 in the bottom of the tubular portion 1-1. The forward triangular lip 17 is bent so that the apex thereof is slightly beyond-the inner edges of the flanges 15, and thus is extended across the outlet end of the slit 16. rThis acts as a guide for inserting the thread which is first directed through the opening 9 and then pulled upwardly to enter the slit 12 and consequently be guided by the fianges 15 through the slit 16, the forward portion of the thread engaging either of the inclined edges of the lip 17 and thus directing the thread into either of the thread guiding channels 18 of the tubular portion 141. At the upper portion of the inner end of `the metal thread guide is provided a tension plate 19, having the thread eye 20, and the diagonal slot 21 which communicates with the eye 20 and opens through one edge of the plate thereby permitting ready access in threading.

What I claim, as new, is:--

1. A shuttle, comprising a body having a bobbin recess opening through the top and bottom thereof and also provided with an inclined bore leading from the forward end of the recess through the bottom of the shuttle, a member removably fitted in the bore, spaced slit tubular portions formed on the member for communication with each other and also for communication with the space between the same, a guide lip on the member and having edges for directing a thread into either tubular portion, and an open eye. extension at the opposite end of the member.

2. A shuttle, comprising a body having a bobbin recess opening through the top and bottom thereof and also provided with an inclined bore leading from the forward end of the recess through the bottom of the shuttle, a member removably fitted in the bore, spaced slit tubular portions formed on the member for communication with each other and also for communication with the space between the same, a guide lip on the member' and having edges for directing a thread into either tubular portion, and an open eye extension at the opposite end of the member, saidY body being further provided with a slit establishing communication between the bore and the opening of the recess through the bottom of said body.

3. A shuttle provided with a bobbin receptacle open through the top, and having an inclined bore leading from the forward end of the receptacle through the bottom of the shuttle, such bore being open its full length through the bottom of the shuttle, and a thread guide removably mounted. in the bore, and comprising a tubular member having a longitudinal, slot alined with. the bottom opening of the bore, and providing two .thread-guiding Channels, a tension device at the forward end of the tubular member, and athreadl directing means at' the forward end of the tubular member forl direct- Jing the thread into either Channel.

4. A shuttle provided with a forwardly' and downwardly inclined bore, the outlet end of which is toward the point and through JOSEPH F. VAILLANCQURT.
